from Scott Stadler:
“Dr. Kam is excellent! My son is currently in week 5 of 12 of the physical therapy program and has significantly improved his flexibility and speed on the basis. Even my son’s coach commented how much stronger and faster he is. The throwing program is specifically designed as my son had little league elbow with fragments in his growth plate. After 8 weeks of no throwing we sought Dr. Kam’s help. Dr. Kam has put together a program to gradually increase arm strength and correct his body and throwing mechanics. My son is now back playing and his arm is much stronger and his throwing mechanics are now in alignment! We are very much looking forward to completing the 12 week program and continuing the program thereafter. I can’t thank Dr. Kam enough. His interaction with my 12 year old is excellent and I highly recommend him!”

from Scarlette Sander:
“I recently had a physical therapy appointment with Dr. Christian and it was one of the most helpful appointments I’ve had. I was experiencing some issues with my chest and ribs for a while. I’ve seen massage therapists, chiropractors & even life coaches to help with physical/emotional recovery and nothing has worked up until my appointment with Dr.Christian. Not only did he find the main cause of the problem but he knew of the right solution.
I really appreciated how knowledgeable he is in this practice but also how he walked me through every detail of what caused it & how to prevent it again in the future . It’s important to find someone who is truly passionate in their career because it shows they care deeply for your health . I highly recommend scheduling with Dr. Christian!”

from Angela Turner:
“We have been taking our 2026 high school baseball player to see Dr Kam for just about a year now. We originally came seeking help for a strained lower back and chronic neck/shoulder discomfort. Our son had actually been under the care of several doctors and had seen a physical therapist for his neck pain. It was never resolved. The level of care and expertise that Dr Kam provides has been invaluable. Seeing someone who specializes in sports physical therapy and working with baseball players is something we could not get through our regular doctor. We now see Dr Kam on an ongoing basis because sports rehab and physical health is critical to an athlete who is working towards the next level. Dr Kam provides a very unique and specialized service to each client depending on their needs and goals. We are so thankful for his knowledge and the support he provides our high school baseball pitcher. I truly don’t know where we would be without his care. Not only does Kam provide us with superior physical therapy services but he truly cares about our son and not only his physical well being and athletic performance but also his mental health. Beyond thrilled that we found Dr Kamren Ackerman.”

from Maxx Coupal:
“Working with Dr. Kam has completely changed my development as a baseball player. In one year, every part of my game improved and the results speak for themselves.
My 60-yard dash dropped from 8.55 to 8.29, my throwing velocity jumped from 74 mph to 78 mph, and my hitting exit velo climbed from 78 mph to 86.5 mph.
Even my strength numbers took off:
• Pull-ups: 4 → 6
• Push-ups: 20 → 34
Every session is personalized, intentional, and focused on making me better in ways that actually matter on the field. I feel faster, stronger, more explosive, and more confident. If you’re a baseball player who wants real results, Dr. Kam is the person you need in your corner.”

“Christian is a great physical therapist. He is filled with knowledge & you can tell by the way he practices the care that he has for his clients. I truly appreciate the skills & knowledge he has, it definitely gives me an ease of mind with any injury I have!”

from Joe Gilmartin:
“Dr Kam is truly a gift to the PT community and those fortunate enough to work with him. In July 2023 I took my son to see Dr Kam due to an injury from pitching. With in seconds he knew exactly what it was but recommended an xray. After the xray it confirmed exactly what he said it was. Dr Kam immediately began a series of PT treatments. His compassion, professional and course of treatment were truly amazing. My son is healed completely from his injury and doing great. Dr Kam was responsive and attentive to questions concerns and our needs. Highly recommend him. He’s one in a million. Hard to find a human being as genuine kind and to top it off extremely intelligent in his profession.”

from Michaella Elad:
“Christian is amazing!! I’ve had years of PT, torn ACL and LCL and to be honest I’ve always struggled trusting PTs because of my experiences. Right away Christian was very understanding, caring and really listened to all of my needs. I highly recommend going to him. With the help of Christian I know I’m going to be stronger than ever! Thank you so much!”

from Serena Santillanes:
“Kam is not only a competent physical therapist providing thorough care and medical expertise, but he has been a mentor and advisor to my son about how to stay healthy, reduce the chances for injury, and how to create a weekly athletic plan that maximizes productive play time with strategic rest. Kam is an indispensable resource and great person. We see him weekly, even when no injury is present as prehab and plan to work with him virtually in the transition to college baseball. My son has not only received Kam’s care through injury and come back stronger as a result, but Kam has taught my son how to take care of his body proactively. I highly recommend Kam!”

from Bardia Fd:
“I’ve been to probably 50 physical therapists in all over the U.S., including Squat University and MoveU But I believe Christian is better than all of them. I’m currently working with Christian on my compensations (upper cross syndrome, low back pain, difficulty breathing, tight traps and thoracic area) and I’m beginning to and hoping to get small improvements. In my opinion, Christian is one in a dozen. From my understanding, he has specialty and residency in the spine, which not many physical therapists have. I highly recommend going to him to see if he can help you. He’s solid 👍🏼”
